[PATCH] drm/i915: Fix race in __i915_vma_remove_closed

i915_vma_reopen checked if the vma is closed before without taking the lock. So multiple threads could attempt removing the vma. Instead the lock needs to be taken before actually checking.

[PATCH] drm/ttm: fix ttm tt init fail when size exceeds kmalloc limit
by Yang Wang 21 Apr '22

21 Apr '22

if the __GFP_ZERO is set, the kvmalloc() can't fallback to use vmalloc() to allocate memory, when request size is exceeds kmalloc limit, it will cause allocate memory fail. e.g: when ttm want to create a BO with 1TB size, it maybe fail.

[RFC PATCH v2 00/10] RFCv2: nested AVIC
by Maxim Levitsky 21 Apr '22

21 Apr '22

This patch series implement everything that is needed to use AMD's AVIC while a nested guest is running including ability of the nested guest to use it, and brings feature parity vs APICv. Compared to v1 of the series, there are lot of fixes, and refactoring. This version still use unconditional read-only apic id, which will be addressed in the next version. For the last patch, which allows to avoid cleaning is_running bit in physid pages as long as it is possible, I measured what would happen in a worst case: - A malicious guest runs with 2 vCPUs pinned, its first vCPU pounds on ICR sending IPIs to the 2nd vCPU and 2nd vCPU scheduled out forever and not halted (something that should not happen with Qemu though) - A normal guest with single vCPU is pinned to run on the same CPU as the 2nd vCPU of the first guest. The normal guest continued to run, but was observed to run about 40% slower. Therefore AVIC doorbel is strict by default but if the admin policy is to pin guests and not allow them to share a physical cpu, then strict doorbel can be set to false and that does improves the nested (and not nested as well) AVIC perf futher. Suggestions, comments are welcome.

21 Apr '22

v11: 1. Drop accepted patches. 2. Rebase to chunkuang.hu/linux.git mediatek-drm-next. 3. Drop DSI compatible in mtk_drm_drv.c because of depenency. 4. Drop DPI compatible in mtk_drm_drv.c because we will use compatible of MT8192 for MT8186. v10: 1. Rebase to 5.18-rc1 2. Drop "dt-bindings: display: mediatek: add aal binding for MT8183". I will move it to another series. v9: 1. Revise [1/5] dt-bindings: display: mediatek: add aal binding for MT8183. v8: 1. Revise [1/5] dt-bindings: display: mediatek: add aal binding for MT8183.

Hi folks: Here is the PR of gvt-next. Thanks so much for the patience. Mostly it includes the patch bundle of GVT-g re-factor patches for adapting the GVT-g with the new MDEV interfaces: - Separating the MMIO table from GVT-g. (Zhi) - GVT-g re-factor. (Christoph) - GVT-g mdev API cleanup. (Jason) - GVT-g trace/makefile cleanup. (Jani) Thanks so much for making this happen.

[PATCH v2] drm/msm/dp: enhance both connect and disconnect pending_timeout handle
by Kuogee Hsieh 20 Apr '22

20 Apr '22

dp_hpd_plug_handle() is responsible for setting up main link and send uevent to notify user space framework to start video stream. Similarly, dp_hdp_unplug_handle is responsible to send uevent to notify user space framework to stop video stream and then tear down main link. However there are rare cases, such as in the middle of system suspending, that uevent could not be delivered to user space framework. Therefore some kind of recover mechanism armed by timer need to be in place in the case of user space framework does not respond to uevent. This patch have both dp_conenct_pending_timeout and dp_disconnect_pending_timeout are used to stop video stream and tear down main link and eventually restore DP driver state to known default DISCONNECTED state in the case of timer fired due to framework does not respond to uevent so that DP driver can recover itself gracefully at next dongle unplug followed by plugin event.

[PATCH 4/4] drm/amd/pm: use bitmap_{from,to}_arr32 where appropriate
by Yury Norov 20 Apr '22

20 Apr '22

The smu_v1X_0_set_allowed_mask() uses bitmap_copy() to convert bitmap to 32-bit array. This may be wrong due to endianness issues. Fix it by switching to bitmap_{from,to}_arr32.

The Display SubSystem IP on the ti's am65x soc has an additional register space "common1" and services a maximum of 2 interrupts. The first patch in the series adds the required updates to the yaml file. The second patch then reflects the yaml updates in the DSS DT node of am65x soc.
